Ayako, a normal high-school girl caught up in the experiment of an enigmatic genius, is divided in two. In the midst of the confusion of sharing her life, she remembers her sister who had died suddenly. What lies beyond the feelings she remembers and the feelings she’s forgotten…

The premise reminds me of the Calvin and Hobbes comic where Calvin makes multiple other Calvins. While that comic plays it for laughs, this one takes a more introspective look at what it would be like to have another "self" with you.

At first the main character really enjoys having 2 selves. I mean, who is easier to get along with than yourself? Gradually she reveals more about her past though, especially regarding her sister, and things start to take a more sinister turn. The story has some great potential here, and I'll keeping with it for now. The art is fairly simple and typical, but works well with the story.
